PHAK-CH3: Aircraft Construction & Composites

In this episode, we explore the evolution of aircraft construction, from early welded-tube truss structures to modern stressed-skin and composite designs. We break down the differences between truss, monocoque, and semimonocoque construction, including how bulkheads, stringers, formers, and stressed skins work together to create strong, efficient airframes.
We also examine the growing role of composite materials such as fiberglass, carbon fiber, and epoxy resin, and why they have transformed aircraft design through weight savings, corrosion resistance, aerodynamic efficiency, and improved fatigue performance. Finally, we look at the unique challenges composites present for pilots, technicians, and inspectors—including hidden impact damage, heat and chemical sensitivity, water ingress, lightning protection, and specialized repair requirements.
From the foundations of aircraft structures to the advanced composite airframes of today, this episode explains how materials and construction methods continue to shape the performance, safety, and future of aviation.
